Whitefly Killer  is supplied as 10 cards of parasitised whitefly pupae containing the tiny parastic wasp of whitefly; Encarsia formosa. These minute wasps emerge from the pupae on the cards to search for whitefly pupae to parasitize. Once they have located them, they lay an egg inside the whitefly pupae, which turns it black in colour and kills the whitefly. The parasitised whitefly pupae then goes on to produce a new Encarsia formosa wasp. This process is one of the oldest forms of biological control and has been used for many years, especially by tomato growers. It has a huge advantage over traditional chemical  pesticide control in that the whitefly are not able to become resistant to attack by these tiny parasites.

The key to sucess is making sure the following is adhered to;

  • Encarsia formosa are only active at temperatures of 17C plus. Do not expect much activity from the parasites at temperatures below this.
  • If infestations of whitefly are already noticeable before introduction, apply a spray of SBPI or similar physical acting  based product to the heads of the plants prior to introduction of Whitefly Killer
  • Introduce Whitefly Killer before whitefly are in high numbers. Weekly introductions will be needed to control serious infestations [ Try Whitefly Killer programme BIO-01-27]
  • Open the Whitefly Killer pack inside the area where you are going to apply
  • Hang the cards evenly over the area of plants to be treated and not in direct sunlight
  • The Encarsia will emerge from the pupae on the cards within a few days. The pupae do not look very different after they have emerged, although if you look closely you can see a small hole where the wasp has emerged from.
  • Do not spray systemic pesticides prior or during use of Whitefly Killer, as they will harm and reduce Encarsia formoa numbers.

Please note it takes the parasitised whitefly pupae 2-3 weeks to turn black in colour after introduction. It is suggested that if using on tomatoes that any lower leaves removed are left in the greenhouse for a week to allow any Encarsia on them to emerge.
